About

Flowering between June and September, Scarlet pimpernel is a common arable weed and is most famous for being the emblem of the fictional hero of the same name. It is sometimes also known 'Old man's weathervane' or 'Shepherd's weather-glass' as the flowers close when atmospheric pressure falls and bad weather approaches. Scarlet pimpernel can be found in arable fields and gardens, on coastal cliffs, roadside verges and chalk downlands.

What to look for

Scarlet pimpernel has red flowers with five petals, each fringed with many tiny hairs; sometimes its flowers can be blue. Its leaves are unstalked and oval, sitting on trailing stems.

Where to find

Widespread across the UK, but scarcer in Scotland.
